Under the distributor cap I get spark from the coil nipple but after putting new cap and rotor on I still get no spark to plugs. Back tracked to the cap and still no spark coming from cap. Could this be a weak coil or timing issue or am I missing something. Just for background the car was sitting for about a year not running put new battery in it because it was shot did tune up ran great for 3 days then the 4th day was a little weak on get up and go but still ran good parked it came out next morning to take it to car wash started fine idled for about 2 minutes then died and hasn't started since

Hello, since you are currently not getting any spark. Are you able to test to see if you are getting fuel (injector pulse)? If you are not getting spark I would remove the distributor cap to make sure the ignition rotor has not broken which can happen if the cap is not installed correctly. Here is how to test the distributor which has the ignition module, crankshaft and camshaft position sensors. You can get a rebuilt unit from amazon for about $90.00 fyi. Check out the images (below). Let us know how it goes

Have not checked the injector plus however I do hear them click but first I started with the spark and I do have a weak spark from the coil nipple that goes from the distributor to the cap it has the self contained type. I do have a spark from there however it looks to be a weak spark. Now I changed the distributor cap and rotor and it still isn't getting spark to the wires I checked by connecting a wire from the cap were the plug wire goes and holding the other end close to ground and no spark so I was wondering what would cause it to not make it from the rotor to the plug wire after replacing rotor and cap sorry if I don't explain well enough makes since in my head at least

Check coil and coil wire leading to cap that may be bad 5000 ohms per foot. And wiggle it around.

You may want to check the timing also.
